Question

What does the airbag, used for safety of car driver, contain?

(a) Sodium bicarbonate

(b) Sodium azide

(c) Sodium nitrite

(d) Sodium peroxide

Answer 1

The correct option is: (b) Sodium azide

Explanation:

Sodium azide is used in airbag, used for safety of car driver. Under room temperature, sodium azide is a stable compound. However, when heated by an impulse it disintegrates to produce sodium and nitrogen. It only takes about 50-100 grams sodium azide to produce enough nitrogen gas to fill a normal airbag for driver.
